Solutions Overview

According to the application requirements of the mining video surveillance system, Huashu Communication has developed a simple and reliable solution, using HS-3210A-2GSFP gigabit industrial Ethernet switch to build the core network. HS-3208A-SS-SC and HS-3206A-SS-SC 100Mbps embedded switching unit networks are used underground and above the well. Super Ring technology is used to form redundant ring networks for both the core network and underground and above the well networks to ensure normal data transmission and system operation in case of fiber optic cable failure. According to the on-site environment, the HS-E3312L single channel embedded network extender can be selected to transmit data over long distances through ordinary cables such as twisted pair cables, telephone lines, and coaxial cables, greatly reducing system costs and construction difficulties while ensuring data transmission speed and quality. At the end of the system, the underlying devices can be directly connected to the HS-3206A-SS-SC 100Mbps embedded switch through the RS-232/RS-485/CAN bus to complete the transmission of business data such as video and broadcast communication.
